In this study, we isolated a 25-kDa novel snake venom protein, designated ablomin, from the venom of the Japanese Mamushi snake (Agkistrodon blomhoffi). The amino-acid sequence of this protein was determined by peptide sequencing and cDNA cloning. The deduced sequence showed high similarity to helothermine from the Mexican beaded lizard (Heloderma horridum horridum), which blocks voltage-gated calcium and potassium channels, and ryanodine receptors. Ablomin blocked contraction of rat tail arterial smooth muscle elicited by high K+-induced depolarization in the 0.

The large-conductance, voltage-dependent and Ca 2+ -dependent K + (BK) channel links membrane depolarization and local increases in cytosolic free Ca 2+ to hyperpolarizing K + outward currents, thereby controlling smooth muscle contractility. Constitutive deletion of the BK channel in mice (BK )⁄ ) ) leads to an overactive bladder associated with increased intravesi-cal pressure and frequent micturition, which has been revealed to be a result of detrusor muscle hyperexcitability.

Concept: Generators convert mechanical energy to electric energy. Motors convert electric energy to mechanical energy. The construction of motors and generators are similar. Every generator can operate as a motor and vice versa. The energy or power balance is : Generator: Mechanical power = electric power + losses Motor: Electric Power = Mechanical Power + losses.
